Notification guide

Will you receive a notification when someone is online on WhatsApp?

WhatsApp does not have a built-in alert for a contact coming online. A third-party status alert is created by that service from the transitions it records.

WhatsApp online status

When you open a chat, if the privacy settings allow it, you may see the word “online” beneath the contact’s name. WhatsApp does not send a standard real‑time notification for this information.

Users can tie their online visibility to their last‑seen preferences, so the online indicator may not appear the same way for every contact.

How is a SeenRadar notification different?

SeenRadar generates its own in‑app alert based on the status changes it can record. It is not a notification sent by WhatsApp or verified by WhatsApp.

An alert indicates only a recorded status change. It does not show whether the monitored person sent or read a message, or who they communicated with.

If you're not receiving notifications

  • For browser alerts, grant notification permission in a supported browser and keep the SeenRadar tab open and connected.
  • Check the contact’s online or offline switch. Online and offline alerts are included in the 24-hour trial and in Premium, on the web and in Telegram.
  • Verify that your network connection is working.
  • Consider that the person's status visibility may have changed.
FAQ

FAQ

Does WhatsApp itself notify you when someone comes online?

No. WhatsApp only shows “online” under the contact’s name while you have the chat open and the person’s privacy settings allow it.

Does a SeenRadar alert mean the person is chatting with someone?

No. An alert only shows a recorded online transition. It does not show whether a message was typed or read, or who the person is talking to.

Why am I not receiving alerts?

For SeenRadar browser alerts, check permission, connection and that the tab remains open. Check the number’s online or offline switch and that your trial or Premium is active. Hidden online status is not recorded, and recording or delivery can be delayed.
